Detailed description：
Since a few month ago I haven't been able to change brightness of the keyboard on Asus TUF A15 FA506QM with default FN + Up/Down arrow keys.
Updating BIOS changed nothing
Also serial number in BIOS seems to have been changed to a wrong one: SSN123456789012345

The problem might be different but the result is the exact same, all my hotkeys are working fine except the Fn+up/down to adjust the brightness of the keyboard's backlight.

Unfotunately the troubleshooting didn't help...

If you have any other ideas, I'm happy to hear about it !

Thanks
